Furthermore, the utility model discloses still provide following subsidiary technical scheme:
the threaded armor pipe is a stainless steel flat wire threaded armor pipe.
The light rat-proof home-entry optical cable further comprises a water-resistant layer arranged between the butterfly cable unit and the stainless steel strip armor layer.
The water-resistant layer is a water-resistant tape or a water-resistant yarn.
The butterfly cable unit further comprises a reinforcement member located within the inner sheath.

Compared with the prior art, the utility model has the advantages of: through set up the cladding in the outside screw thread armour pipe of optic fibre and the cladding at the outside stainless steel band armor of butterfly cable unit in butterfly cable unit, carry out dual metal protection to the inside optic fibre of optical cable, improved the protection against rodents performance of optical cable greatly, strengthened the anti side pressure ability of optical cable simultaneously and laid the span, improved the use reliability of optical cable, the construction installation of being more convenient for.
Drawings
Fig. 1 is a schematic cross-sectional view of the light rat-proof home-entry optical cable of the present invention.
Detailed Description
The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings.
As shown in fig. 1, the light rat-proof home optical cable according to the preferred embodiment of the present invention includes a butterfly cable unit 1, a water-blocking layer 2 disposed outside the butterfly cable unit 1, a stainless steel armoring layer 3 coated outside the water-blocking layer 2, and an outer sheath 4 coated outside the stainless steel armoring layer 3.
The butterfly cable unit 1 includes an optical fiber 10 located at the center, a threaded armor tube 11 covering the optical fiber 10, an inner sheath 12 covering the threaded armor tube 11, and a reinforcement 13 disposed in the inner sheath 12.
The number of the optical fibers 10 is not limited, and may be one or multiple, and two optical fibers are illustrated in fig. 1 and are all inserted into the threaded armor tube 11. The threaded armor pipe 11 is a stainless steel flat wire threaded armor pipe, so that the rat bite prevention performance of the optical cable can be enhanced, the internal optical fiber 10 can be effectively protected, and the side pressure resistance of the optical cable can be improved.
The inner sheath 12 is extruded outside the threaded armor pipe 11, and the reinforcing members 13 are arranged inside the threaded armor pipe 11, in the embodiment, the number of the reinforcing members 13 is two, and the reinforcing members are symmetrically arranged on two sides of the threaded armor pipe 11. The reinforcing member 13 may be made of GFRP (glass fiber reinforced plastic), which is light in weight and high in strength, and can effectively reinforce the tensile strength of the optical cable.
The waterproof layer 2 wraps the inner sheath 12, so that moisture can be effectively prevented from invading the butterfly cable unit 1, and the waterproof performance of the optical cable is improved. The water-resistant layer 2 can be a water-resistant tape or water-resistant yarn, and a wrapping mode of combining winding and laying and flat drag and drop or bidirectional cross winding and laying can be adopted, so that the water-resistant layer 2 has high-efficiency waterproof performance.
The stainless steel strip armor layer 3 is formed by longitudinally wrapping stainless steel strips outside the water-resistant layer 2, can effectively improve the rat bite prevention performance of the optical cable, protects the butterfly cable unit 1 inside, can also enhance the side pressure resistance performance of the optical cable, and improves the laying span of the optical cable, so that the side pressure resistance capacity of the optical cable can meet the short-term 3000N/100mm, and the laying span can meet the span within 50 meters.
The outer sheath 4 is made of polyethylene. In the prior art, the outer sheath of the optical cable is usually made of low-smoke halogen-free materials, and after long-time wind blowing and sun drying, the outer sheath of the optical cable can be aged and cracked, even is powdery, so that the transmission performance of the optical cable is seriously influenced, and the service life of the optical cable is shortened. In this embodiment, the outer sheath 4 is made of polyethylene material, so that the ultraviolet resistance can be enhanced, and the service life of the optical cable is longer, generally up to 25 years.
The utility model discloses a light-duty protection against rodents introduces optical cable through set up the cladding in butterfly cable unit at the outside screw thread armour pipe of optic fibre and cladding at the outside stainless steel band armor of butterfly cable unit, carries out dual metal protection to the inside optic fibre of optical cable, has improved the protection against rodents performance of optical cable greatly, has strengthened the anti side pressure ability of optical cable simultaneously and has laid the span, has improved the use reliability of optical cable, the construction installation of being more convenient for.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
